v2.3.2

Codex reviewer reliability + Claude reviewer model upgrade.

• fix(codex-code): pin codex-version 0.135.0 — stops the floating-latest --server-info handshake flapping (#78)
• ci(claude-code): bump reviewer model to claude-opus-4-8 (#77)

Callers should re-pin to this tag. Codex callers can also bump model gpt-5.4 → gpt-5.5 (validated accessible).
